My website is so big that it has 30 subdirectories. Which suggests to me that I should take a month or so to tweet a link to one of those each day. I’ll start tomorrow. For now, here’s the link to the site:

Seeking Depth in Algebra 2
Bad teaching has given that course a bad rep. Done right, it helps prepare *all* students for more advanced work.
